There isn't a trouble code that indicates a bad coil... there are misfire codes that can possibly lead to a plug, coil, fuel injector, low compression, or a number of other things. it is possible to have 2 more bad coils-if youve had the engine compartment detailed and they got them wet, that'll do it. other than that it is hard to see 2 coils going at 1 time. spark plugs themselves are more likely.
